Chief ME for NYC revealed the autopsy findings Wednesday saying the fetus “had been non-viable for at least 24 hours" before delivery

The medical examiner added that there was no criminality and no charges will be filed

The Office of the Chief Medical Examiner for NYC revealed the autopsy findings Wednesday, saying the fetus, which was discovered Aug. 7 aboard an American Airlines flight, “had been non-viable for at least 24 hours prior to the unanticipated delivery.”

The medical examiner added that there was no criminality and no charges will be filed.

American's flight tracker showed the plane, flight 1942, left Charlotte at 8:56 p.m. and arrived at LaGuardia's Terminal B at 10:44 p.m. Aug. 6. Photos from the scene showed Port Authority officers surrounding the jet on a tarmac Aug. 7 after it apparently was removed from the hangar for further investigation.

Detectives tracked down the mother at a hospital in Brooklyn after flight attendants recalled seeing two young women sitting near the back of the plane go into the bathroom after it landed, law enforcement sources familiar with the investigation told News 4 New York.

The mother, whose name has not been released, told detectives she had been bleeding for a day or two while they were on a trip in Jamaica. Their flight stopped in Charlotte, North Carolina, before heading back to New York -- and when the plane did land in Queens, the mother said she was uncomfortable.
